WATER OR FLUSH TANK FOR WATER-CLOSETS, 84.0.

isP'EQIEICATION forming part 01' Letters Patent 130. 340,226, dated April 20, 1886.

Application flied June 9,1885.

To all whom it 111.01g concern:

Beitknown that I, WILLIAM E. LINDSLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia 5 and State of Pennsylvania, have invented certain new and useful Improvements in XVater or Flush Tanks for Vater-Olosets and other Fixtures, of which the following is a specification, reference bein'g had therein to the accompanying drawings, wherein Figure 1 is an elevation of a flushing tank or reservoir and service-pipe embodying my improvements, and showing the application of a water-closet thereto. Fig. 2 is a vertical section, partly in elevation, of the overflow float-valve and casing and part of the flushtank, drawn to an enlarged scale. Fig. 3 is a detailvertical section of check-valve in supply-pipe for the flush-tank.

My invention has relation to that class of water-closet or other flush tanks or reservoirs having an overflow or floatvalve attachment for automatically closing the air vent or pipe of the tank when it is filled, and which in like manner opens said vent or pipe as the tank is emptied; and it has for its object simplicity of construct-ion of parts, as hereinafter described and claimed.

In the drawings, A represents a tank or res- 0 ervoir, having a supply or service pipe, B.

Aindicates the overflow float-valve attachment, composed of top and bottom plates, D and O, float-valve E, tubular body F, and fastening-rods G.

The bottom plate, 0, is formed with a shoulder, 0, on its upper side for the reception of a gasket, 0', edge lugs, c, radially arranged, having openings 0, and a central opening, 0", terminating in a threaded nozzle, 0", which screws 0 into an opening, a, in the top of the tank A.

' The top plate, D, is formed with a shoulder,

d, on its under side, to receive a gasket, (1, side or edgelugs, d radially arranged, and having openings d", to register or align with the open- 5 ings c in lugs 0 on plate 0, a amber, h, on

its upper side, in which is a bridge, h, and having outlet-opening If, which is exteriorly threaded at h to receive a coupling, h, of a pipe, I. The latter may lead to a chimney or wall, 00, '(see Fig. 1,) or elsewhere, as desired,

and it forms an air-pipe for the attachment A and tank A.

Serial No. 168,135,

(No model.)

In the center of plate D, upon its lowerside, is a teat or stud, (1, having an opening, (72, which leads into chamber 72, to form acommunication between air-pipe I and tank A. The lower end of opening (1 in stud cl is bored out dish shape, or made conical, to form a seat, (1", for a correspondiugly-shaped valve,E, secured or provided with a stem, 6, fluted on its out- 6O side and passing upward through opening d To the top of stem .12 connects a screw, 6, which passes through opening I? in bridge h. The head 6 of screw 6 rests upon the bridge h, as shown in Fig. 2, to hold valve E in a 6 suspended condition when off its seat.

Valve E is preferably made with a bottom plate or flange, c", in which are inserted a number of downwardlyproiecting flexible rods or wires, 0, which are adapted to bend around a glass or other ball, a, as shown, to secure it to valve Fl, said ball serving as a lloat for the valve.

The body F for the attachment A is made of glass or other material, as desired, and is 5 inserted between the plates 0 D, its edges contacting with and sinking into the gaskets c d, to form tight joints therewith when itand the plates are connected together by the boltrods G, passing tl'irough the openings 0 d in 8; lugs c d of the plates 0 D, respectively.

The float-valve attachment A prevents overflow from the tank, for as soon as it is tilled the water or liquid passing into body or chamber F rises therein until it reaches the ball or .85 float 0 when it ascends and elevates or moves valve E to its seat (1, to close the outlet-opening (1 in top plate, D, or the passage to the ven-t-pipe I. As soon as the water in tank is used or drawn oft, the float and valve drop 0 and unseal outlet (1 to restore communication between the tank and vent-pipe, to admit air to the former as the water is escaping from the same. To prevent backliow from the tank, its pipe B is provided with a check-valve, b, at or near its end, or in advance of apipe-connection therewith, said check-valve being shown more plainly in Fig. 3.

The tank, with its attachment, serves fora Ioc flush-tank for water-closets or other fixtures, as indicated at K in Fig. 1, in which case the valve is of the closet has a pipe-connection, k, with the pipe B. Upon opening the closetvalve is the water from tank A passes to and flashes the eloset-bowl,the check-valve b meanwhile closing while the flushing takes place.

The foregoing described construct-ion of parts, it willbe noted, provides a service-pipe and closet-connection for a tank float-valve attachment, the parts of which are separable from one another, so that repairs or replacement of broken parts can be easily and inexpensively accomplished. The tank is always tilled without overflowing, and when filled backflow therefrom is avoided, and a body of water is always ready to be immediately drawn from said tank.

What I claim isl. A detachable overflow attachment for flushing tanks or reservoirs, composed of step arable top and bottom plates, atnbular body, a float-valve having a loose or sliding connection with a bridge formed in a chamber on said top plate, a vent-pipe for said chamber, and serew-bolts for securing said plates and body t ogether,sn bstantially as shown and described.

2. A flush-tank attachment, A., composed i of plate 0, having screw-nozzle a, shoulder c, gasket or packing c, and bolt-holes c, tubular body F, plate D, having central opening, (1 valve-seat ll, shoulder d, gasket or packing d, bolt-holes d, and chamber 71 having ventpipe I, and bridge h, with opening if, the valve E, having screw-connection a, with bridge h, float e, and fastening-wires e, and bolts G, for securing said parts in position relatively to one another, substantially as shown and described.

3. In combination with tank A, having float-valve attachment A, a single service or an inlet and outlet pipe, B, having check valve 7), and a valved branch pipe, k, above said check-valve, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
